Wavetrac

**spordee1** · 07-08-2010, 12:58 PM

Installed a 35 spline Wavetrac, used Yukon Aluminum thru bolt center and 411 gears with Moser axles and housing. I expected it to be just a little rough, especially with 35 spline axles, but it was extremely smooth riding. I have a Spec 3 clutch with an LS6 under the hood and the Wavetrac with 411 gears complemented them very well. It feels almost like riding in an automatic even though it is a T56.

Congrats. I've heard a lot of good things about the Wavetrac. When and if my TruTrac goes, I might look into that set-up.

I will try and get pics up soon, I still have to work on TA and LCA'S and a few other things. My engine builder did all of the work, now I will have to go to my local garage will take care of the small adjustments.

Installed tunnel mount torque arm, removed factory torque arm from transmission. I could feel every vibration and metal on metal turned it into sound with the tunnel mount. I went back and installed one-quarter inch neoprene under the mount and once again my wavetrac is nice and smooth. At times you can feel the 35 spline when you put it into gear, but my car is still totally a DD. In fact with the 411 gear, it is very enjoyable with 3rd and 4th gear excelleration when just driving around.

what does that posi cost?

ballpark figures, $1000.00 - wavetrac differential to moser, $600.00 axles to moser, 9" housing w/ LCA brackets, painted, ends, TA mount, $500.00 LS1 TECH, Aluminum center $325.00 - Yukon, $150.00 for 411 ring & pinion gear - ebay, pinion support $80.00, yoke $100.00. $200.00 for used DS at LS1 TECH, basically I spent $4k with labor and TA and mount, sway bar, and still considering LCAs and panhard bar.
I did find one neat trick, the tunnel mount brought all of the vibrations into the car after I removed the factory TA from the transmission. I put one quarter inch of rubber between the car and the mount. eliminated 95 percent of the noise and vibration.
last, I have 400 RWHP, I have never enjoyed driving the car so much as with 411 gears and a Spec 3 clutch. I have plans to drop an LS3 in the next year.

What was your source for the neoprene bushings? I also have some noise transmitted into the cabin from my tunnel mount. It's not terrible, but I wouldn't mind toning it down just a bit.

I was trying to explain to my mechanic about the bushings, and he went in the back and found some old fan belts and doubled them up. He had not heard about tunnel mount vibration or rubber bushings under the mount. Metal is an excellent conductor of sound vibration. But long story short, home made or store bought, either will work very well. Mine were home made.
